Measurement and Analysis of the Next-day Air Shipping Environment for Mid-sized and Lightweight Packages for DHL, FedEx and United Parcel Service

摘要

The past decade has shown a great increase in the number of direct to consumer shipments of products and packages. As a result, parcel delivery companies like DHL, FedEx, UPS and the USPS have strengthened their presence in air transport. Using cargo planes, they route packages from various destinations to large airport hubs, where they sort millions of packages and ship them to their destinations the next morning. There is a continuous need to quantify what happens to these packages as they are handled both manually during collection and delivery and on large high-speed conveying and sortation equipment at hubs. This study measured and compared shock and drop events for these carriers during next-day and 2-day shipping service.
